I'm assuming that you are talking about sequences <3
In the context of a recursive formula where we have "n-1" in sub-index of "a", you can think of "a" as the previous term in the sequence. In the context of an explicit formula like "-5+2(n-1)" "n-1" represents how many times we need to add 2 to the first term to get the nth term.
Dw if you don't understand, sequences and functions isn't an easy topic
Your answer is D. 7 hope this works
20 kg bag of bananas for 10 dollars
This is the given situation in which in every 20 kilogram of bananas, the costs is 10 dollars.
Now, let us calculate how much each kg of banana costs will. Let’s solve for the unit rate of this given data:
=> 20 kg bag of banana
=> 10 dollars = cost
Now, let’s divide this to get the answer that we need.
=> 20 / 10
=> 2 bananas per dollars = 2 banana/dollars
Or 10 / 20
=> 0.5 dollars/1kg of banana
